APPARATUS FOR MAKING SOAP.

SPECIFICATION forming part of Letters Patent no. 05,988, dated June 21, 1898.

Application filed September 1, Serial No. 650,268. (No model.)

To all whom it may concern:

Be it known that I, FRITZ ARLEDTER, en-

gineer, a citizen of Switzerland, and a resi-,

or knives, and simultaneously the particles of resin ascending along with the lather are being melted by a number of slitted hot metal plates. By this means an effectual partition of the resin into the smallest particles is obtained, theresult being resinous soap with greatly-liberated resin. At the same time the expulsion of the gases generated in boiling makes the boiling process much' more thorough than hitherto and also considerably shorter. i

In the drawings, Figure 1 is a side view of the boiling apparatus. Figs. 2, 3, 4, and 5 are detail views of the same. 7

The resinous soap is made in the usual manner in a boiler a, heated by indirect steam through the steam-jacket b.

c is a bottom-stirrer forming the nethermost part of a shaft 61, which during the working of the bottom-stirrer is at e coupled to another shaft f. Around this shaft rotates a third shaft or sleeve 9. The shafts f and g are by means of some transmissiongear made to rotate in opposite directions to each other. In the drawings this is shown as attained by means of the two bevel-wheels h and 2', respectively fastened to the upper ends of the shafts f and 9, being made to rotate in opposite directions to each other by a third bevelwheel 70, inserted in the gearing and moved from the motor by the belting Z.

Around the shaft g is a sleeve m, sliding up and down, yet so that it always follows the rotating motion of the shaft g. The sleeve on is by a connecting-rod a connected with another sleeve 0, which in the same manner s sliding up and down on its shaft I f and rotatin g with this. Figs. 2 and 3 are a side view and plan View showing how the sleeve m may be connected with its shaft g. This latter is shown in square section and passes through the corresponding sleeve m, which is square inside. Springs 1? keep, through friction, the sleeve min its position, and by means of the pivoted lever 7",loosely geared round the sleeve through a loose ring q, the sleeve m may be adjusted up and down, thereby carrying the lower sleeve 0, that may slide on the shaft f by means of stop and notch. The rod n, connecting the sleeves, may at the ends be fastened to a loose ring 8 and 25, respectively surrounding the sleeves m and o.

Curved arms to to extend from the sleeves m and 0, ending nethermost in the same height,and carrying here plowshaped irons or knives o o and w w. Fig. 4. is a detail plan view of one of these knives fastened to its arm n, and'Fig. 5 is a plan view of the whole arrangement of all the knives, (here four,) turning, of course, their edges in the direction of the motion. This direction is, as will be understood from what has been said above, opposite for each pair, as indicated by the arrows in Fig. 5.

0a a; a: are fixed metal plates fitted in the most suitable way to the boiler a and preferably adjustable up and down. The plates in Fig. 1.

In my apparatus, as described above, a rapid and intense partition of the millions of gas-bubbles will beeffected by means of the fixed slitted plates w, in combination with the very effective opposite motion of the knives 'v 20. mass during the boiling will be considerably reduced, and as a result the temperature may, through admission of steam, be raised, whereby the process is accelerated, while at the same time a thorough separation of the saponified and non-saponified resin particles is effected. The resin particles ascending from below strike in circular motion constantly against the hot metal plates at, where they melt, and by means of the rotating motion of the knives c to they are continually carried farther through the slits y and thoroughly In this way the usual ascent of the are fitted with longitudinal slits y, as shown 7 ICO for rotating the shafts and means for raising and lowering the agitators consisting of the sleeves about the shafts and connected together with means for raising and lowering the said sleeves, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 2d day of August,

FRITZ ARLEDTER.
